CHAPTER 7 COMMUNICATION OF THE ETHERNET ADAPTER MODULE

7.3 IP Communications over CC-Link IE Field Network (IP Packet Transfer Function)
7.3.4 Connection to CC-Link IE Field Network
● Details on the routing parameters
Refer to the user’s manual for the master/local module used.
● When an external device is connected to an Ethernet adapter module
Set the routing parameters so that communications transmit through the master station.
Communications from an Ethernet adapter module automatically transmit through the master station. The communication
routes must be the same for data sending and receiving; therefore, configure the setting so that communications transmit
through the master station.
Proper setting
Improper setting
*1 An IP communication test related error (error code: 4A28
H
) occurs in the IP communication test.

The setting is not required
because the Ethernet

Because the communication route for data sending is different
from that for data receiving, an error occurs.
